Letters Patent iva-111,153, dated January 24, 1871.

I'MPROl/EMENT IN SlZlNG-MACHINES;

The Schedule referred to these Letters Patent and part of the same.

To all whom it may concern:

13e it known that I, ALBERT H, STURGIS, of Lewiston, in the county of Androscoggin and State of Maine, have invented a new and useful Improvement in. Silng-Machines; and Ido hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawing and to theletters of reference marked thereon.

This invention is an improvement on Bulloughs sizing-machine, and consists in certain details of construction, which will be fully described hereinafter.

In the drawing- A y Figure l represents aside elevation of myimproved machine;

Figure 2, a plan view;

Figure 3, a partial sectional view of the revolving brush and'its bearings; and

' Figure 4, a sectional side view of the eccentricbearing. p

'lo enable others skilled in the art to make and use my invent-ion, I will now proceed to describe i'ullyiits `construction and manner of operation. p'

A represents the frame-work of the machine, which may be of any suitable construction.

B B B represent spools, held in propel' bearings "at the rear of' the machine, which contain the yarn to be sized.

The yarn upon leaving these spools passes over rollers b b and down into the size-box C, and about the rollers contained therein.

c c represent rollers held in suitable bearings Vin the vframe, which rest upon the upper `rollers in the size box. I

From the size-box the yarn passes beneath the revolving brush and roll, the construction and am ngement of which will be more fully described hereinafter, to drying-cylinders E E', and thence over various rollers c c to the bea-m F, upon which it is wound.

f As my invention does not relate particularly to the sizing ot' the yarn, nor to the arrangement of the rollers for conducting it properly, nor tothe arrange ment of the drying-cylinders, these parts will not beV more particularly described, the arrangement and location of them being immaterial. The parts, however, which I do claim as my invent-ion will now be described in detail. e

H represents -the brush, which consists of acylinder having a central shaft resting in suitable bearings at each end, which is provided with longitudinal rows l.of brushes', separated at suitable intervals, as shown.

The bea-rings of shaft hI consist of boxes h1 h1, inl i which the shaft is eccentrically located, as shown,

which are capable of revolving'movemcnt in the journals h2 in standards It".

Gonnecting with the ,boxes are arms h4, united by rod hi; by means of which the former are simultaneously moved when desired.

By means of this` construction the brush may be Y nals It?, to rise near the upper.

I represents a'tray or trough rest-ing on suitable standards above, and in rear of the center'of the brush,

, -whichisfilled with water, and provided with a cloth for conveying its contents to the'brush for the purpose of dampening and cleansing it.

J represent-s an independent roll' located in front of the brush, for taking up any loose ends and enabling the operator to secure them properly.

K 'represents a clearer, arranged below and slightly.

in rear of the center of the brush, which serves to hold v the yarn in place while the brush is doing its work.

A The specialadvautage of the construction described is the arrangement of this clearer, or it maybe aroll,

it` desired, in such relation to the brush4 that the yarn shall be properly held while the brush is doing its work. It should be so placed that the brush will strikethe ribbon or sheet of thread forward of the clearer, at or ne'ar a point where aline plumb-from `the center of the brush would' intersect the sheet of thread.

Heretofore yarn treated without the arrangement of the clearer has been tape-like and uneven, and,

consequently, more or less unfit for use, this result being caused by the separation of the iibers of" the yarn bytheaction ot' the brush in consequence of its not being properly held when being operated upon.

By means of my improvement, however, this dificultyis entirely obviated, and perfectly-dressed yarn or its equivalent, when the clearer is arranged in such relation to the brush that the latter will act upon the y sheet of thread-forward of the clearer at or near a point in line vertically below the center of the brush, as v described. l

This specification signed and witnessed this ALBERT H. STURGIS.
